SURFACE CONDENEEE.

My present invention relates to a surface condenser and moreparticularly to that type of surface condenser in which provision ismade for the expansion and contraction of the condenser tubes due to thevariation in heat to which the apparatus is subjected. The object of myinvention is the provision in a surface condenser of an expansion jointplaced between the condenser shell and at least one of the tube platesor sheets and preferably connecting the same whereby the ends of thecondenser. tubes may be shrunk in the tube plates and the tube platewith which the expansion joint member is associated may shiftlongitudinally of the tubes to provide for the expansion and contractionthereof and wherein the construction is such as to eliminate any leakagebetween the condensate and the circulating water thereby increasing theeficiency of the apparatus. The construction furthermore is such as to(in tirely eliminate the use of a double bonnet at the expansion joint.end of thecondenser as heretofore employed in apparatus of this t pe.

In the drawingFigure 1 is a longitudinal section illustrating thecondenser provided with the improved expansion joint member. Fig. 2 isan enlarged section illustrating this construction of the joint.

Fig. 3 is a sectional view illustrating another form of the invention,and Figs. 4, 5 and 6 are also sectionalviews showing the further formsof the invention.

Referring to the drawing and particularly to Figs. 1 and 2, thecondenser shell 10 may be of the usual orany desired form and asiscustomary is provided at its oppositely disposed ends with flanges 11and12. As illustrated. at one end of the condenser there is a tube plate13 and a bonnet or cover 14. These parts are connected to each other andto the shell at this end thereof by means of bolts 15 passing throughtheflan re 12 of the shell, the outer portion of the tube plate and aflange provided for this purpose in the peripheral portion of the bonnet14. A plurality of tubes arranged in any nested relationship areindicatedat 16 and at this end of the condenser are suitably fixed inthe tube plate by means shrunk therein or otherwise. N

At the other end of the condenser as illus trated in these figures,there is a movable or shittahlie tuba plate 13b The opposite ends of thetube 16 are suitably secured in this tube plate by being shrunk thereinor otherwise. This tube plate is connected to a shell by an expansionjoint member 18. As illustrated, this expansion joint member is annularand conforms in outline With the end of the shell of the condenser. Theinner portion of the expansion joint member is connected to the outerportion of the tube plate by means of a flat ring 19 and suitable studbolts QOor-ot-herwise. The outer portion of the expansion joint memberextends and lies betweenthe flange 11 at this end of the condenser shelland a flange 21 on a Water bonnetor cover 22. These parts are connectedto each other and to the shell of the condenser by means of bolts 23passing through aligned bolt holes provided therefor in the flanges 11and 21 and the outer portion of the expansion joint member 18. It willbe understood that the joints between the expansion joint member and thetube plate are made tight and that a similar condition exists in thejoint between the outer portion vision for an interior recess 25 forthere ception of the outer or of thetube plate 17. y

In the construction of the condenser as indicated in Fig. 3, thecondenser shell interiorlyis provided with a rib or fiance connected towhich is a bracket 26. Slidably mounted on the bracket 26 are one ormore guides 2'? which are suitably connected to the tube plate28 at thisend of the shell. The expansion joint member in this structure isindicated at 29. The outer portion of the expansion joint member isconnected to the internal flange of the condenser shell by means of aring 30 and bolts 81, certain peripheral portion of which bolts may alsobe employed to secure the bracket26 in place on the internal flange.

The inner portion of the expansion joint member 29 is connected tothetube plate 28 by means of a ring 32 and a series of bolts 83, certainof which may also be employed to secure the tube plate 28 to the guidememher or members 27.. As illustrated in this fig are at the drawing theenter edges lit? of the expansion joint member may be ribbed asindicated at 34 and 35, making it possible to more readily secure thesame in position and to maintain it. in place in relationship to theinternal rib andthe tubeplate.

In the construction shown in Fig. 4: the end of the condenser shell 36is provided with a flange 37. The outer portion of the expansion ointmember 38 is placed between the outer surface of this flange 37 and theinner surface of a ring 39. These parts are connected to each other andsecured together by'means of a series ofsuitablebolts 10. in thisconstruction the tube plate is indicated at 4:1. The inner portion ofthe expansion joint member abuts against the outerportion of this tubeplate and the expansion joint member and the tube plate are secured inposition between a ring a2 and the flange 48 ofa bonnet or cover 4- bymeans of a series of bolts 45 or otherwise. It will be understood thatin this structure the water box includes the bonnet and the tube plateand that these parts are shiftable longitudinally of the tube due to theexpansion and contraction thereof, and furthermore that the movableparts at the end of the condenser may be suitably supported.

Int-he construction shown in Fig. 5, the condenser shell 4:6 is providedat one end with a boss 47, and a Water box 48 with a similarboss 49. Inthe expansion joint member 50employed in this construction there is acentrally disposed and outwardly extending rib or loop 51. Then theouter-portions of the expansion joint member 50 bears against the:lacesof the bosses 4-7 and 49 and respectively are secured in positionthereon by means of a. ring 52 and a series of bolts58, anda ring 54-and a corresponding series of bolts 55. In this structure the bonnet 48is provided with an internal flange 56 against which the outer portionof the tube plate 57 is secured by means of aserics of bolts 5801'otherwise. In this structure like that shown in Fig. 4, the bonnet andtube plate are shiftable longitudinally of the tubes due to theexpansion and contraction thereof and may be suitably supported in thismovement.

In the construction shown in Fig-6, the condenser shell 59 at one-endthereof is provided with an internal bracket 60 and a. guide or guidemembers 61 are connected to the tube plate 62-by means of rivets asindicated or otherwise. Lyingbetween the face of the bracket 60 and theadjacentsurface orsurfaces of the guide or guide members 61 there is aroller or ball bearing 63 upon which the guides and tubeplate areshiftable .due tovthe expansion-and contraction of the tubes. In thisstructure the expansion joint member is indicated at 64. The outerportion thereof is secured to the condenser shell by means o-fa ring 65and a series of bolts 66, while the inner portion thereof is connectedto the tube plate (352 by means of a ring 67 and a suitable series ofbolts (38.

It will be understood that the several coustructions herein shown anddescribed are more or less merely illustrative of the inven- 'tion asother and similar constructions may be employed without departing fromthe spirit thereof. It will furthru'morc be understood that theexpansion joint member may be made of metal or 'i'ulu'ic or :1combination of the same or other materials which will serve the intendedpurpose. and that in all instances the connectitms between the expansionjoint member and the parts of the. apparatus with which it is sociuicilare made tigl'it irrespective of the term in whirl) the invention may bepracticed so as to prevent any leakage between the exhaust steam orcendensate and the water or other circulating medium employed in theapparatus.
